Definitions

  • the invention relates to a support structure for motor vehicles according to the preamble of claim 1.
  • Such a support structure for motor vehicles which can be found in EP 0 255 749 B1, comprises a sandwich construction floor which is formed in one piece with a front end wall. An approximately U-shaped stem structure is attached in front of the front wall, which is also made in a sandwich construction. Columns can be attached to the floor, which support a roof structure. Only when the floor is supplemented with this roof construction does a sufficiently rigid safety passenger cell emerge. In the event of a frontal impact of the motor vehicle, the front structure is first used to absorb impact energy before the safety passenger cell is damaged.
  • the well-known support structure is less suitable for vehicles with an open body, such as roadsters or convertibles.
  • the object of the invention is to provide a support structure for motor vehicles of the type specified in the preamble of claim 1, which can be made sufficiently stable without a roof structure while maintaining a good crash behavior.
  • the support box provides improved support of the stem structure on the bottom of the support structure, so that e.g. in the event of a frontal crash, a desired sequence of deformations is achieved in which the stem structure acts in a particularly good manner as an energy-absorbing crumple zone and the safety passenger cell with the floor is largely retained in its shape. Due to its stable design, the support structure can be used in particular for vehicles with different structures.
  • the lightweight panels of the support box allow carrying out tasks for components arranged in this area.
  • the upper lightweight panel of the support box can take on the function of a beam under the instrument panel and the cross beam under the cowl.
  • An end wall that extends almost over the entire width of the floor can be manufactured inexpensively by the simple geometry and can be fastened well to the side walls. If a transitional area of the front wall is directed obliquely upwards from the floor, a sliding surface is created for both the engine and the front wheels in the event of a frontal impact, with which excessive front wall intrusions can be avoided.
  • Two longitudinal beams with an angled cross-section enable a rigid design of the stem structure, which is particularly well attached to the support box when the rear ends of the vertical plate legs are supported over almost the entire height. If the vertical plate legs extend at least over half the height of the end wall, the longitudinal members can reliably be avoided in the event of a frontal collision. A particularly simple and inexpensive to produce side member is created when a transverse plate leg over about a right one Angle is connected to the associated vertical plate leg. Overall, the longitudinal beams result in a particularly good protection due to their shape and arrangement, for example in a frontal impact with a small width coverage of the vehicles involved.
  • a box-shaped structure stiffening the stem structure is created with the side members and the support box, especially if the front module comprises a frame construction with an upper and lower cross member.
  • the stem structure also has corresponding advantages for the rear structure.
  • a box-shaped structure stiffening the rear structure is created, which is particularly stiffened by a plate arrangement made of lightweight building boards.
  • a tunnel attached to the floor is provided between the front wall and the rear partition, the floor is designed to be particularly rigid.
  • forces occurring on the stem structure or rear structure can be distributed particularly well over the entire support structure.
  • a lightweight inner door shell results in a stable door, which is due to the largely parallel arrangement Side wall can be easily sealed against the support structure.
  • Lightweight construction boards can be very quickly and correspondingly inexpensively by extrusion of light metal alloys e.g. manufacture from aluminum. For sound and heat insulation, it can be expedient to foam the hollow chambers of the lightweight panels after cutting to length.
  • the supporting structure can be composed of essentially flat plates which are light but extremely rigid, in contrast to the conventional shell construction made from deep-drawn sheet metal, no large-sized shapes are required. This means that even vehicle series with smaller quantities can be economically manufactured, especially since add-on parts for cladding the support structure, in particular from plastic, can be produced quickly and inexpensively. Standardized support structures can be implemented that are still suitable for different vehicle concepts.
  • a very rigid connection of the support structure to the roof structure is achieved by the receptacles fastened to the support structure, with which columns of a roof structure can be attached.
  • the recordings serve as a support for the door hinges.
  • Fig.la, b each in a perspective view obliquely from the front or from the side of a support structure of a motor vehicle according to a first embodiment of the invention
